Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study was to compare the subthalamic nucleus(STN) with the globus pallidus internus(GPi) as a stimulation target for deep brian stimulation(DBS) for medically refractory dystonia.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this prospective randomized controlled study,elecrodes were bilaterally implanted in STN and Gpi of 40 patients with dystonia.
